-
activationAlgorithm
=
MEAN
-
This attribute specifies the activation algorithm for memory overload protection.
Default value is MEAN. Allowed values are MEAN and CONSECUTIVE.
MEAN: average of the measuring period compared against the upper threshold value. When the average value is above the upper threshold value, the corresponding memory overload actions are activated.
CONSECUTIVE: consecutive samples in the measuring period have to be above the upper threshold before the memory overload actions are activated.

-
deactivationAlgorithm
=
CONSECUTIVE
-
This attribute specifies the deactivation algorithm for memory overload protection.
Defalut value is CONSECUTIVE. Allowed values are MEAN and CONSECUTIVE.
MEAN: average of the measuring period compared against the lower threshold value. When the average value is below the lower threshold value, the corresponding memory overload actions are deactivated.
CONSECUTIVE: consecutive samples in the measuring period have to be below the lower threshold before the memory overload actions are deactivated.

boolean

-
enable
=
false
-
If true, memory overload protection is enabled.
Default value is false. Applicable only if MmasOLPService enable is set to true.

-
lowerThresholdValue
=
80
-
This attribute specifies the memory usage threshold level for HTTP requests.
Default value is 80 percent. Allowed values are 0 to 100. The value must be set lower than the upperThresholdValue. Any HTTP requests received when the system is operating beyond the specified threshold remain in a standard overload protection state. The MMAS default in this state is to respond with a 503 Service Unavailable HTTP error containing a Retry-After header using the retryAfterInterval attribute value specified in the MmasOLPService class. This action is programmable via the MMAS OLP API by creating a custom OLP filter or valve. Applicable only if MmasOLPMem enable is set to true and the MmasOLPMem upperThresholdValue had been reached.

-
maxLowerThresholdValue
=
90
-
This attribute specifies the memory usage threshold level for the HTTP requests.
Default value is 90 percent. Allowed values are 0 to 100. The value must be set lower than the maxUpperThresholdValue. Any HTTP requests received when the system is operating beyond the specified threshold remain in a maximum overload protection state. The MMAS default action in this state is to respond with a 503 Service Unavailable HTTP error containing a Retry-After header using a value three times higher than the value specified for the retryAfterInterval attribute value in the MmasOLPService class. This action is programmable via the MMAS OLP API by creating a custom OLP filter or valve. Applicable only if MmasOLPMem enable is set to true and the MmasOLPMem maxUpperThresholdValue had been reached.

-
maxSamplingRate
=
2
-
This attribute specifies the sample rate in seconds for updating threshold levels for memory usage.
Defalut value is 2 seconds. Allowed values are 1 to 60 seconds.

Percent50To100
noNotification |
-
maxUpperThresholdValue
=
95
-
This attribute specifies the memory usage threshold level for the HTTP requests.
Default value is 95 percent. Allowed values are 50 to 100. Any HTTP requests received when the system is operating beyond the specified threshold trigger a maximum overload protection state. The MMAS default action in this state is to respond with a 503 Service Unavailable HTTP error containing a Retry-After header using a value three times higher than the value specified for the retryAfterInterval attribute value in the MmasOLPService class. This action is programmable via the MMAS OLP API by creating a custom OLP filter or valve. Applicable only if MmasOLPMem enable is set to true.

-
measuringPeriod
=
10
-
This is the measuringPeriod attribute for MmasOLPMem class MO.
This attribute specifies the measuring period in seconds needed before threshold is raised for memory usage.
Default value is 10 seconds. Allowed values are 2 to 1200.

upperThresholdValue
=
85
-
This attribute specifies the memory usage threshold level for HTTP requests.
Default value is 85 percent. Allowed values are 50 to 100. Any HTTP requests received when the system is operating beyond the specified threshold trigger a standard overload protection state. The MMAS default action in this state is to respond with a 503 Service Unavailable HTTP error containing a Retry-After header using the retryAfterInterval attribute value specified in the MmasOLPService class. This action is programmable via the MMAS OLP API by creating a custom OLP filter or valve. Applicable only if MmasOLPMem enable is set to true.
